Honorless

I literally just realized that Nalthis' magic qualifies as such, lol

Scadrial is very spooky too with flesh devouring shapeshifters, weird carcass scavenging beings with various animal body parts, brutes with no skin, a dude with spikes driven through their eye sockets.

Spooky!

I don't think they'd give many names to other worlds. That'd just be messy narratively. They'll stick with the Cosmere standard names. 

Yeah but say a nalthian went to Roshar and pointed at a coulor and went like “That’s hyponextonic red” and the other dudes like “wtf that’s grey” because on Nalthis their social network is all about coulor they would have so many different names for certain colors and less for others.
